XTrace launches open-source encrypted vector DB

XTrace solves a major privacy gap in the RAG stack by ensuring embedding vectors never exist in plaintext on third-party infrastructure.

• –Direct search on encrypted vectors prevents "Vec2Text" attacks where plaintext is reconstructed from numerical embeddings
• –Client-side key generation means the server stores only ciphertexts, providing a true zero-trust architecture
• –The x-mem module introduces a belief revision system for AI agents, handling conflicting data via Subjective Logic
• –Significant latency overhead is the primary trade-off, currently making it a niche tool for high-privacy/low-speed use cases
• –Open-source release under Apache 2.0 allows for independent audits of the cryptographic implementation
